Ch 12 Rad Protec

Manage of Imaging personnel Rad Dose

QuestionAnswer
Annual occupational effective dose 50mSv (5rem) for whole body exposure during routine operations
Annual effective dose 1mSv (.1rem) for individals in general population
CumEfD limits a radiation workers whole body lifetime effective dose to his or her age times 10mSv (years=1rem)
GSD Rad workers can receive a later EqD than the general public w/o altering the genetically significant dose
4 ways or reducing scatter that also reduces the occupational hazard for the radiographer 1.use of beam limitation devices 2.high kvp low mas 3.appropriate beam filtration 4.reduction of repeat exams
Fetal EqD does not exceed .5mSv
Protecting from leakage radiation lead lined metal diagnostic type protective housing
3 ways to protect the radiographer during fluoro 1.beam collimation 2.high speed image receptor 3.cumulative timing device
Protecting during portables radiographer should stand at right angles to the xray beam scattering object (the pt) line
Time, distance, shielding; which is the most effective Distance
xray beam is 100kvp-lead? lead should be at least .25mm
Control booth barrier This barrier must extend 7ft upward from the floor and must be permantently secured
Diagnostic type protective tube housing protects radiographer and pt from off focus and leakage radiation by restricting the emission of xrays to the area of the useful or primary beam
Leakage radiation radiation generated in the xray tube that does not exit from the collimator opening but rather penetrates thru the protective tube housing and to some degree thru the sides of the collimator
Workload W the quantity that best describes the weekly radiation use of a diagnostic xray unit
Occupancy factor T used to modify the shielding requirement for a particular barrier by taking into account the fraction of the workweek during which the space beyond the barrier is occupied
Controlled area the hall only radiation workers use
Uncontrolled area the hall the pt use
